Michael Gove, the doctrinaire ignoramus now in charge of UK environmental policy
It does not matter very much that Michael Gove mistakenly imagines that Boyle’s law is some kind of a fundamental principle. It matters a very great deal, however, that he saw fit to tell teachers that they should teach it as such. It is a sad reflection on the British educational system that Gove, an Oxford graduate, thinks that Newton wrote the laws of thermodynamics, thus showing unawareness of the difference between 17th-century mechanics and 19th-century molecular statistics; the difference between the age of sail and the age of steam. But again, that need not in itself mattered too much. What does matter at many levels is his wish to have “Newton’s laws of thermodynamics” incorporated into the physics curriculum. In both cases, the shameful ignorance displayed is not in itself the major problem. The real concern is Gove’s willingness to impose his ignorance on those who know better, a willingness that led the National Association of Head Teachers, hardly a group of dangerous radicals, to vote no confidence in him. I have written on these topics before, most recently when he bid to become Prime Minister (“Why Michael Gove is not fit to lead anything”) but thought when that bid failed that I could let Gove lapse into the security that he so richly deserves.
Not so, alas. Gove is now Secretary of State for the Environment Food and Rural Affairs. Not topics on which I am an expert, so I will simply hand readers over to someone who is; Miles King at A New Nature Blog:
Last week I wrote about Michael Gove’s surprise arrival as Secretary of State for the Environment Food and Rural Affairs. There is so much more to write about this, but time is limited and I will not be able to cover everything in one piece.
Gove obviously has achieved notoriety amongst the Education establishment, by driving through unpopular reforms to the National Curriculum and to the testing regime. As these reforms have only recently been implemented, the benefits, or damage they cause will only become clear in the years to come.
As a parent with children in the education system I will see personally what Gove (and his comic-book villain sidekick, Dominic Cummings) has done for the future of my family, aside from his (and Cummings’) leading role in Brexit.
His subsequent stint at the Ministry of Justice was too short for him to have achieved anything, either way. Perhaps…

Why Michael Gove is not fit to lead anything
There are mistakes due to ignorance. There are mistakes due to misunderstanding. And finally, there are mistakes that show ignorance, misunderstanding, complacency, and arrogance.
The news that Michael Gove wants to lead the country sent me back to what I wrote about him almost exactly 3 years ago. He was, of course, talking through his hat, and we all do that from time to time. But he did this while telling the rest of us, in his then capacity of Education Secretary, what to do and how to teach. Now it may not matter that Michael Gove has only a limited grasp of physics (actually, I think it does, when the physics of climate change underlie the most important single challenge facing us), but it matters enormously that a would-be future Prime Minister considers his ignorance a qualification.
Anyway, here is the gist of what I wrote back then, which is suddenly attracting a surprising number of hits, given its age:
The Education Secretary said “What [students] need is a rooting in the basic scientific principles, Newton’s laws of thermodynamics and Boyle’s law.” [reported here]. He has been widely criticized for this (e.g. here and here), but it’s still worth discussing exactly why what he said is so appallingly wrong, on at least four separate counts. In the unlikely event that Mr. Gove ever reads this, he may learn something. Muddling up the laws of motion with the laws of thermodynamics is bad enough. Muddling up an almost incidental observation, like Boyle’s Law, is even worse, especially when this muddle comes from someone in charge of our educational system [well, not mine actually; I’m glad to say I live in Scotland], and in the very act of his telling teachers and examiners what is, and what is not, important.
Okay, from the top. Newton’s laws; Gove probably meant (if he meant anything) Newton’s laws of motion, but he may also have been thinking of Newton’s law (note singular) of gravity. [I went on to summarise both Newton’s laws, and Newton’s law, and to explain how the combination of these explained the hitherto mysterious phenomenon of planetary motion and related it to the motion of falling bodies on Earth; an intellectual achievement not equalled until Einstein’s General Theory of Relativity]
But what about the laws of thermodynamics? These weren’t discovered until the 19th century, the century of the steam engine… [I briefly described them]
If you don’t immediately realize that Newton’s laws and the laws of thermodynamics belong to different stages of technology, the age of sail as opposed to the age of steam, and to different levels of scientific understanding, the individual and macroscopic as opposed to the statistical and submicroscopic, then you don’t know what you’re talking about. Gove’s blunder has been compared to confusing Shakespeare with Dickens. It is far, far worse than that. It is – I am at a loss for an adequate simile. All I can say is that it is as bad as confusing Newton’s laws with the laws of thermodynamics, and I can’t say worse than that.
And regarding Gove’s description of Boyle’s Law as “basic”, I had this to say:
He [Gove] has been justly mocked for confusing Newton’s laws with the laws of thermodynamics. But the kind of ignorance involved in describing Boyle’s Law as a “basic scientific principle” is far more damaging.
Disclosure: I taught Boyle’s Law for over 40 years, and it gets three index entries in my book, From Stars to Stalagmites.
Bottom line: Boyle’s Law is not basic. It is a secondary consequence of the kinetic theory of gases, which is basic. The difference is enormous, and matters. Anyone who thinks that Boyle’s Law is a principle doesn’t know what a principle is. (So Gove doesn’t know what a principle is? That figures.)
Mathematically, the Law is simply stated, which may be why Mr Gove thinks it is basic: volume is inversely proportional to pressure, which gives you a nice simple equation (P x V = a constant) that even a Cabinet Minister can understand. But on its own, it is of no educational value whatsoever. It only acquires value if you put it in its context [in the kinetic theory of gases], but this involves a concept of education that seems to be beyond his understanding…
Educationally, context is everything, the key to understanding and to making that understanding worthwhile. A person who decries the study of context is unfit for involvement with education.
Even at Cabinet level.
And, I would now add, completely unfit for making major decisions in these interesting times.

Boyle’s Law is not a principle; so does the UK Education Secretary know what a principle is?
What [students] need is a rooting in the basic scientific principles, Newton’s laws of thermodynamics and Boyle’s law. [Education Secretary Michael Gove, reported here].
He has been justly mocked for confusing Newton’s laws with the laws of thermodynamics (e.g. here and here and, by me, here). But the kind of ignorance involved in describing Boyle’s Law as a “basic scientific principle” is far more damaging.
Disclosure: I taught Boyle’s Law for over 40 years, and it gets three index entries in my book, From Stars to Stalagmites.
Bottom line: Boyle’s Law is not basic. It is a secondary consequence of the kinetic theory of gases, which is basic. The difference is enormous, and matters. Anyone who thinks that Boyle’s Law is a principle doesn’t know what a principle is. (So Gove doesn’t know what a principle is? That figures.)
Reasoning: Boyle’s Law states that if you double the pressure on a sample of gas, you will halve the volume. Boyle thought this was because the molecules of gas repel each other, so it takes more pressure to push them closer together, and Newton put this idea on a mathematical footing, by suggesting an inverse square law for repulsion, rather like his inverse square law for gravitational attraction. They were wrong.
Mathematically, the Law is simply stated, which may be why Mr Gove thinks it is basic: volume is inversely proportional to pressure, which gives you a nice simple equation (P x V = a constant) that even a Cabinet Minister can understand. But on its own, it is of no educational value whatsoever. It only acquires value if you put it in its context, but this involves a concept of education that seems to be beyond his understanding.
Now to what is basic. Boyle’s Law is now explained using the kinetic theory of gases. This describes a gas as a whole lot of molecules, of such small volume compared to their container that we can think of them as points, each wandering around doing their own thing, and, from time to time, bouncing off the walls. It is the impact of these bounces that gives rise to pressure. If you push the same number of molecules (at the same temperature) into half the volume, each area of wall will get twice as many bounces per second, and so will experience twice the pressure. Pressure x volume remains constant.
Actually, Boyle’s Law isn’t even true. Simple kinetic theory neglects the fact that gas molecules attract each other a little, making the pressure less than what the theory tells you it ought to be. And if we compress the gas into a very small volume, we can no longer ignore the volume taken up by the actual molecules themselves.
So what does teaching Boyle’s Law achieve? Firstly, a bit of elementary algebra that gives clear answers, and that can be used to bully students if, as so often happens, they meet it in science before they have been adequately prepared in their maths classes. This, I suspect, is the aspect that Gove finds particularly appealing. Secondly, some rather nice experiments involving balancing weights on top of sealed-off syringes. Thirdly, insight into how to use a mathematical model and, at a more advanced level, how to allow for the fact that real gases do not exactly meet its assumptions. Fourthly, a good example of how the practice of science depends on the technology of the society that produces it. In this case, seventeenth century improvements in glassmaking made it possible to construct tubes of uniform cross-section, which were needed to measure volumes of gas accurately. Fifthly … but that’s enough to be going on with. Further elaboration would, ironically, lead us on to introductory thermodynamics. Ironically, given the interview that started this discussion.
Educationally, context is everything, the key to understanding and to making that understanding worthwhile. A person who decries the study of context is unfit for involvement with education.
Even at Cabinet level.
UK Education Secretary says students need to know how Newton invented thermodynamics [!]
I would like to say that Michael Gove shows a knowledge of what counts as basic science that is some 300+ years out of date, but that would be too kind.
Gove said there had been previous attempts to make science relevant, by linking it to contemporary concerns such as climate change or food scares. But he said: “What [students] need is a rooting in the basic scientific principles, Newton’s laws of thermodynamics and Boyle’s law.” [Times interview, reported here]
As many readers will know, but the Education Secretary clearly doesn’t, Newton’s laws describe the motion of individual particles. Thermodynamics is intrinsically statistical, and was developed over a century after Newton’s death. Boyle’s Law is not a basic scientific principle, although it is a corollary of the basic principles followed by (ideal) gases. And here we have someone ignorant of these elementary facts, in a position of enormous power, telling the schools how to teach, and the examination boards how to examine.
And in this same interview, he says he wants schools to form chains and brands, like businesses. Satire falls silent.
